After receiving his second DUI within a decade, Olympian Michael Phelps has decided to go to rehab.

The 29-year-old tweeted what he intends to do next, stating:

"The past few days have been extremely difficult. I recognize that this is not my first lapse in judgment, and I am extremely disappointed with myself. I'm going to take some time away to attend a program that will provide the help I need to better understand myself. Swimming is a major part of my life, but right now I need to focus my attention on me as an individual, and do the necessary work to learn from this experience and make better decisions in the future."
